Abstract: PURPOSE:To obtain a holding force in accordance with a load, by incorporating a piston in the upper section of a cylinder vertically arranged in the arm mechanism of a robot used to automatize a doffing work in a thread pick-up process, by means of a spring. CONSTITUTION:An arm mechanism 12 elevates a receiving bed 9 by means of a first cylinder 5 arranged in an arm 10, and holds a paper tube 2 and a cake 3, so that it adjusts its holding force in accordance with the difference between the diameters of the paper tube 2 and the cake 3, or a difference in the stroke of the first cylinder 5, and as well the difference between the weights of the tube and cake. That is, when the cake is held, the receiving bed 9 is raised under the pressure of the first cylinder 5 so that the receiving bed 9 is at first made into contact with the cake 3, and thereafter, a spring 8 in a second cylinder 6 is yielded by the weight of the cake 3. Accordingly, the second cylinder 6 and a piston 7 are abutted together, and thereby the cylinder pressure in the first cylinder 5 is directly transmitted to the cake 3, and is maintained.

Abstract: PURPOSE: To enable searching of musics accurately despite short intermusic intervals by leading out the counter signal of tape and intermusic interval detecting signal and storing the count value of the counter at the leading-out of the intermusic interval detecting signal thereby controlling tape running.  
     CONSTITUTION: A Hall element 8 is provided in proximity to the ring magnet 5 provided to a take-up reel 5 and the output of this element 8 is counted as α signal. When the end of a music is reached, the intermusic interval signal is drawn out from a magnetic head 7 in an intermusic interval detecting circuit 10 to provide the β signal. These are supplied to a microcomputer to perform high speed stopping and reproduction run controlling. Hence, the count scale of the counter at the time when the end of the music is reached and the stop signal β is generated has beforehand been stored and the portion having been overun is fed back by reversing the motor revolutions then stopping the motor, thus the searching of the next music may be accurately performed even if the intermusic intervals are short.

Title: Optimum controller
Inventor: MITSUNAKA TOSHIO
IPC: B21B37/00
Filed: 1985-02-06
Abstract: PURPOSE:To attain the stable control despite the variance of the waste time by always securing the loop gain increased up to a level near the limit of stability in response to the behavior of the changing waste time and maximizing the capacity of a control system. CONSTITUTION:The actual thickness of a member 1 to be rolled and sent from a roll stand 2 is measured by an output side thickness gauge 3. Then the output signal of this measurement is applied to a multiplier 44 of a monitor AGC4. The multiplier 44 gives the rolling speed signal detected by a speed generator 20 to a divider 41 as a denominator and uses the distance L between the stand 2 and the gauge 3 given from a constant setting unit 40a as a numerator to calculate the waste time. A combuting element 42 uses this wastetime to calculate an angle frequency omega of a point where the phase characteristics of the control system is reduced less than about -180 deg.. A computing element 43 uses the frequency omega to calculate a desired loop gain which is used to obtain the target gain margin of the prescribed control. This loop gain is delivered to the multiplier 44. Thus the AGC4 can always give the optimum gain accordant with a stable operating state to the loop via the multiplier 44.

Title: Agc circuit
Inventor: ICHIHARA MASAKI
IPC: H04J3/00
Filed: 1990-01-30
Abstract: PURPOSE:To attain accurate gain control even to a reception signal whose amplitude level is changed discontinuously at every burst signal by applying the amplitude level of a burst signal of one preceding period to a variable gain amplifier while interposing a delay circuit to apply gain control. CONSTITUTION:A received intermediate frequency signal is applied to an input terminal 1 and then supplied to a detection circuit 3 and a variable gain amplifier 5. The detection output of the detection circuit 3 is smoothed by a filter 4 and retarded by a delay circuit 6 and fed to a variable gain amplifier 5 as a gain control voltage afterward. The variable gain amplifier 5 applies gain control to the intermediate frequency signal fed from the input terminal 1 according to a gain control voltage supplied from the delay circuit 6 and outputted from an output terminal 2 so that the amplitude level of the intermediate frequency signal is kept constant. Thus, the AGC function is realized even in a TDMA system in which the signal is transmitted as a burst signal and the frequency hopping is implemented at a prescribed period at every burst signal.
